Amid low oil prices and burgeoning budget deficits, Saudi Arabia annonced it was considering listing the state-owned oil giant Aramco on the Saudi stock exchange.Aramco is the world's largest company in the oil business and the backbone of the Saudi economy.But the oil business is not creating enough cash these days. Even with the low oil price, the numbers associated with Aramco highlight why this could be such a significant initial public offer.Saudi Aramco has crude reserves of about 260bn barrels of oil, which is more than 15 percent of the world's proven oil reserves. If it went public, it could become the first listed company valued at $1 trillion or more, analysts estimate.Saudi Arabia's $98 billion budget deficit is seen by many analysts as the main reason for the listing, but Saudi officials inists it is part of an attempt to diversify the economy beyond oil and have the private sector play a biger role.So, will auctioning off a slice of Aramco give Saudi Arabia more time to weather the oil price storm?
